as specific example have table t columns customer , date indicating days on individual customers have made purchases: customer | date ---------------------- | 01/01/2013 | 02/01/2013 | 07/01/2013 | 11/01/2013 b | 03/01/2013 b | 08/01/2013 i want add column each pair (customer, date) pair (c, d) , gives number of pairs (c', d') in t such c = c' , 0 <= days(d) - days(d') <= 7 . below table column: customer | date | new_column ---------------------------------- | 01/01/2013 | 1 | 02/01/2013 | 2 | 07/01/2013 | 3 | 11/01/2013 | 2 b | 03/01/2013 | 1 b | 10/01/2013 | 1 as rough idea of steps used solve problem: create table t' possible pairs (c,d) ; left join t onto t' ; create new column: count(date) on (partition customer order date asc rows between 6 preceding , 0 following) ...

i'm using code topic's accepted answer asp.net mvc rememberme but, after log in reopen browser , i'm not logged in. why ? to make answer-able: make sure browser you're using isn't setup delete cache/cookies/session information on close (or @ least add exemption local testing). also, make sure you're not browsing in privacy/incognito mode delete information on close well. for short-term work-around, can keep browser window (at least 1 tab) open , let visual studio open new tab each compilation. should keep session information between tab views (until inevitably close window).

i have app has 2 screens. in first screen there's button opens second screen modal view via modal segue, , has uilabel. i want uilabel have text varies depending on how many times user clicks button (they're hints: user can click button , see hint 3 times). i'm doing following method every time click button: - (void)prepareforsegue:(uistoryboardsegue *)segue sender:(id)sender { if ([segue.identifier isequaltostring:@"tipmodal"]) { quiztipviewcontroller * detailviewcontroller = (quiztipviewcontroller *) segue.destinationviewcontroller; detailviewcontroller.delegate = self; detailviewcontroller.tiptext = self.quiz.currenttip; [detailviewcontroller.numbertipstext settext:[nsstring stringwithformat:@"pistas para la respuesta (usadas %ld de 3)", (long)self.quiz.tipcount]] ; nslog(@"%d", self.quiz.tipcount); nslog(@"%@", detailviewcontroller.numbertipstext.text); } } the last...

this general question regarding unit testing bolts , spouts in storm topology written in java. what recommended practice , guideline unit-testing (junit?) bolts , spouts ? for instance, write junit test bolt , without understanding framework (like lifecycle of bolt ) , serialization implications, make mistake of constructor-based creation of non-serializable member variables. in junit, test pass, in topology, wouldn't work. imagine there many test points 1 needs consider (such example serialization & lifecycle). therefore, recommended if use junit based unit tests, run small mock topology ( localmode ?) , test implied contract bolt (or spout ) under topology? or, ok use junit, implication being have simulate lifecycle of bolt (creating it, calling prepare() , mocking config , etc) carefully? in case, general test points class under test (bolt/spout) consider? what have other developers done, respect creating proper unit tests? i noticed there topology test...

once compiled , ran behave tail call? let rec f accu = function | [] -> accu | h::t -> (h + accu) |> f <| t maybe there easy way test behavior i'm not aware of, might question. i think easier see if not use pipelining operator. in fact, 2 pipelining operators defined inline , compiler simplify code following (and think version more readable , simpler understand, write this): let rec f accu = function | [] -> accu | h::t -> f (h + accu) t now, can read definition of tail-call on wikipedia , says: a tail call subroutine call happens inside procedure final action; may produce return value returned calling procedure. so yes, call f on last line tail-call. if wanted analyze original expression (h + accu) |> f <| t (without knowing pipelining operators inlined), becomes ((h + accu) |> f) <| t . means expression calls <| operator 2 arguments , returns result - call <| tail call. the <| operator define...

if me please, have pcspim simulator on windows 7 pc , want load file , run command prompt, possible print -in cmd window- output shown in pcspim's console after excution? in advance. this hlp file. pcspim supports rich command line argument format. can control core simulator settings, , specify file loaded automatically. command line options available are: -bare/-asm -trap/-notrap -trap_file <file> -delayed-loads -delayed-branches -quiet/-noquiet -mapped_io/nomapped_io -file <file> <args> note -file <file> argument, if specified, must come last. after -file <file> option considered run-time arguments, , saved first time program executed. so -file command need load file. something might create file.txt results in: pcspim -file myfile.ext >file.txt

i trying filter friends based on work history using fql, fql not return results. here fql trying: select uid,username,work user uid in (select uid1 friend uid2 = $myid) , work.employer.id in ($someid) i result - { "data": [ ] } am doing wrong? this because work field doesn't obey other fields due how arrays set each each work object. example strlen(work.employer.id) gives 0. so in short fql doesn't support feature. can try submitting bug report.

my class has property enum . property bound nstablecolumn . typedef enum _status { unknown=0, win, osx } status; in order make sure nstablecolumn shows proper string representation, instead of displaying numeric 0, 1, , 2, use nsvaluetransformer . so unknown becomes "unknown os". win becomes "ms windows" , osx becomes "osx 10.8". table column displays these values correctly. i need sort column using transformed values. if use [nssortdescriptor sortdescriptorwithkey:@"status" ascending:yes selector:@selector(compare:)]; the column sorted in order: unknown os ms windows osx 10.8 which make sense because 0 < 1 < 2. require sorted using string counterparts, make it: ms windows osx 10.8 unknown os how can without changing order of enum? you're using standard compare: method in selector. it's comparing enums. create own m...

i have application had been migrated vb vb.net. in few places in vb there code written using trim operation on non-string datatype. code runs in vb same produce error on migrated code in vb.net.following code snippet dr["n0"].trim() ----where "no" integer or non-string datatype i want identify these places in migrated vb.net code base. how can without minimal effort? efficient idea or technique? just gate these typeof http://msdn.microsoft.com/en-us/library/0ec5kw18.aspx , use debug.alert(); you're going through program alerted (in debug mode).

i've been trying translate this funcformat = funcformat.gsub(/sqrt\((.*)\)/,'math.sqrt(\1)') to in java funcformat = funcformat.replaceall("sqrt((.*))","math.sqrt($1)"); or there way of formatting math text?, example : 2x^2sqrt(x^3/2) 2xpow2sqrt(xpow3/2) thank you, , way i'm new in site. you can use following expression: funcformat = funcformat.replaceall("sqrt\\(([^)]*)\\)", "math.sqrt($1)"); although seems don't need regexes here. simple funcformat = funcformat.replace("sqrt", "math.sqrt"); seems work situation.

i have login script based on php , javascript. couldn't figure out longest time why work in chrome , safari not in firefox or internet explorer. figured out issue html, instead of having regular submit button have image submit. , changing type="image" type="submit" resolves issue. know why , if there's compatible way write following this works: <input name="dologin" type="submit" style="margin-left:90px;" id="dologin3" value="login"> this not: <input name="dologin" type="image" src="login-btn.png" style="margin-left:90px;" id="dologin3" value="login"> if not going using js submit form, input type submit button should submit. if must have image in place of button, position image css setting background of button. no need change input type image. hope helps.
